Title: Simultaneous neutralisation of ion exchange regenerants - requires less neutralising agent and capital equipment
Inventor: KESSLER DIETER P
IPC: B01J49/08
Filed: 1975-10-24
Abstract: Ion exchanger regenerates, esp. in demineralising plants neutralised by regenerating cation exchangers with HCl or H2SO4 or anion exchangers with NaOH. The introduction and dilution of the regerant is effected by water pumps using demineralised water and regeneration of the cation and anion exchangers is simultaneous. The effluents from the exchangers (including the washings) are intensively mixed and passed through a small buffer and control container whose working vol. is =1.2 times the total vol. of the cation and anion exchange resins. The amt. of HCl or H2SO4 used is 96-97% the equiv. amt. required to neutralise the free NAOH from the anion exchange eluate. The HCl or H2SO4 is treated with that quantity of gaseous CO2 before being passed through the cation exchange resin which will buffer and neutralise the 3-4% excess NaOH but is only added after the amt. of HCL or H2SO4 having passed through the cation exchange resin bed is 0.6 of the latter's vol. The amt. of neutralising agent used, control equipment and plant used is reduced and the effluent has a pH of 6.5-8.5.

Title: Cross-talk suppressor for adjacent wires in data processors etc. - makes pulse transit times between connectors equal to pulse rise times
Inventor: BRAECKELMANN WALTER DR ING
IPC: H05K1/02
Filed: 1977-02-10
Abstract: The crosstalk suppressor, for data processing and control systems, is intended for adjacent wires in four pole plug connectors. The length of the wires between two consecutive connectors is so chosen that the transit times of signals along these wires are greater than or equal to half the rise time of the pulses being transmitted. This choice of length considerably reduces the amplitude of any crosstalk. If the plug connectors are mounted on a circuit board at small spacing, bypass conductive paths are formed between connecting points of the plug connectors.
